Apple's current 9.7-inch iPad models use a G/G touch screen structure. The sources said Apple's move to use DITO technology shows the company is looking to bump up its competition in the tablet segment and that it has more adequate supply to the technology compared to one-glass-solution (OGS) technology.

The supply chain for Apple's next-generation 9.7-inch iPad will be similar to the iPad mini's, with Japan-based Nitto expected to supply thin-film materials and Nissha Printing touch screen modules, noted the sources. Taiwan-based TPK will be responsible for the device's lamination while LG Display (LGD) and Sharp will provide panels, added the sources.

The G/F2 touch screen structure will allow for a thinner and lighter device. It's expected that suppliers will be able to produce four to five million units a month through 2013.

It's unclear when Apple might release the iPad 5; however, it is widely expected to feature a design similar to the iPad mini. Apple just released a new 128GB version of the iPad 4.
